What is the mediastinum?

Explanation:
The mediastinum is the central compartment of the thoracic cavity located between the two lungs, and it houses important structures such as the heart, great vessels, trachea, and esophagus. This region is distinct from the lungs, which occupy the lateral parts of the thoracic cavity; from the diaphragm, which forms the muscular floor of the chest; and from the pleural cavities, which are the potential spaces surrounding each lung within the pleural membranes. So, the mediastinum is that central space between the lungs where key thoracic structures are located.
